  2. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    In oxy-fuel cutting, oxidation of the metal being cut (typically iron) produces nearly all of the heat required to "burn" through the workpiece. Oxygen is usually produced elsewhere by distillation of liquefied air and shipped to the welding site in high-pressure vessels (commonly called "tanks" or "cylinders") at a pressure of about 21,000 kPa ...

  3. MAPP gas - Wikipedia

    en.wikipedia.org/wiki/MAPP_gas

    A set of MAPP and oxygen cylinders is used for oxy-fuel welding and cutting.. MAPP gas was a trademarked name, belonging to The Linde Group, a division of the former global chemical giant Union Carbide, for a fuel gas based on a stabilized mixture of methylacetylene (propyne), propadiene and propane.

  4. Gas cylinder - Wikipedia

    en.wikipedia.org/wiki/Gas_cylinder

    For gases that are liquid under storage, e.g., propane, the outlet pressure is dependent on the vapor pressure of the gas, and does not fall until the cylinder is nearly exhausted, although it will vary according to the temperature of the cylinder contents. The regulator is adjusted to control the downstream pressure, which will limit the ...

    A woman in Germany was sentenced to life in prison for murdering her "doppelgänger" in 2022. The victim's family in Algeria found out about the verdict three weeks later.

  9. Oxy-fuel combustion process - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_combustion_process

    The justification for using oxy-fuel is to produce a CO 2 rich flue gas ready for sequestration. Oxy-fuel combustion has significant advantages over traditional air-fired plants. Among these are: The mass and volume of the flue gas are reduced by approximately 75%. Because the flue gas volume is reduced, less heat is lost in the flue gas.
